CSL Cybersecurity: Embedded protection for critical connectivity

Critical systems—like fire, security, EV charging, healthcare, and industrial IoT—need more than just connectivity. They demand built-in security assurances that ensure: 

• Devices remain shielded from public IP scans and external attack surfaces 
• End-to-end encryption protects data in transit against interception or manipulation 
• Hardware and firmware are tamper-resistant, with verified integrity at runtime 
• Real-time monitoring and alerting not reactive incident response 

With IoT threats increasing in both frequency and sophistication, the majority of deployments remain vulnerable due to default insecure configurations and unencrypted data transmission. For example, SIM swapping attacks alone threatens vast IoT estates when weak configurations are exploited, enabling adversaries to hijack connectivity or inject malicious traffic. Public broadband or unmanaged SIMs simply don’t provide this level of protection. Indeed, ensuring the highest level of embedded security is key to our SIM card solutions. For these reasons, our rSIM technology uses Thales to ensure the highest levels of hardware and manufacturing process security and platform integration.

CSL’s cybersecurity combines multiple protective layers to form a resilient shield:

1. Private APNs , VPNs & VLANs
   Connected devices operate on closed, private networks—making them invisible to public scans.  
2. Static IP + NAT1 & ACL2 Controls
   Remote access is locked down through specific, manageable rules—no open ports or wild card exposures. 
3. Encrypted Traffic & Secure Tunnels
   Communication across routers, platforms, and cloud systems remains encrypted end-to-end. 
4. Preconfigured, Hardened Devices
   All CSL routers, SIMs, and broadband units ship locked down—no default credentials, no misconfigurations. 
5. Continuous Monitoring & Response
   CSL’s Connectivity Management Platform tracks usage, health, and anomalies—prompting alerts or interventions before issues escalate. 
6. Compliance & Testing
   ISO 27001 standards, regular pen testing, and vulnerability scanning ensure resilience over time.

This depth of security turns CSL’s connectivity into trusted infrastructure—not just an outsourced utility. 

Protect Critical Infrastructure

A single IoT breach can shut down alarm systems, EV chargers, or healthcare kiosks—impacting safety, compliance, and reputation. 

Reduce Complexity & Risk

No need for inhouse security teams, misconfigured firewalls, or fiddly VPNs. CSL provides a managed, consistent security layer. 

Build Trust with Stakeholders

Systems that meet insurance and regulatory requirements, come with audit trails, and offer visibility build confidence with end users, B2B buyers, and certifiers. 

Future-Proof & Scalable

New threats emerge constantly—but CSL’s architecture and monitoring scale alongside your deployments, without opening new vulnerabilities. 

• Cybersecurity is non-negotiable in critical connectivity—CSL builds it in, not bolts it on. 

• Layered protections extend from physical devices to network architecture and operational monitoring. 

• Customers gain peace of mind, compliance support, and reduced operational overhead. 

• Interconnected systems for alarms, telecare, EV, industrial IoT, and more: CSL protects them all.
